What Do the Different Colors Mean on Google Maps?
Google Maps does not provide a color key or map legend. However, they have published some insight on what their colors mean. Refer to, “Discover the Action Around You with Updated Google Maps“, and “Google Maps Gets New Look“.
Other countries may have additional sets of colors. This is due to those countries having different sets of jurisdictions than compared to the United States or Canada.
Otherwise, here is a breakdown of what each Google Map color represents (for North America only) …
 Light Gray – Boundaries of cities, towns, and villages. In the case of large cities, this often represents the boundaries of all adjoining cities. |
 Lighter Gray – (Just a tad bit lighter) School campuses, including colleges. Does not normally include private, vocational schools (University of Phoenix, et al). |
 Dark Gray – Airports |
 Darker Gray – Military areas |
 Pink – Hospitals and healthcare areas |
 Light Pink – Indian Reservations |
 Light Green – Areas of thick vegetation. Not normally State or Federally owned lands. Usually private property or county-owned lands. In more populated areas, these are often green belts. |
 Green – National Forests, National Parks, State Forests, State Parks, Municipal Parks, golf courses, cemeteries. National Grasslands are often represented in this color, but are also represented in Light Olive (see below). In the case of National Forests and National Parks, these green shaded areas represent the forest’s or park’s larger sphere of influence, and not the actual boundaries. See, “Why is There Private Property Inside National Forests and Parks?” for more detailed explanation. |
 Light Olive – National Grasslands. Note that Google Maps also represents other National Grasslands in Green. There is no logic to this, it’s just an inconsistency on their part. Note, as with National Parks and National Forests, these boundaries represent the Grassland’s larger sphere of influence, and not the actual boundaries. See, “Why is There Private Property Inside National Forests and Parks?” for more detailed explanation. |
 Dark Green – Preservation areas, Protected areas Wilderness areas, National Refuges, or other areas intended for limited human access, or scientific study |
 Blue – Bodies of water, lakes, rivers, ocean |
 Yellow – Shopping centers, tourist areas |
